Claro API Challenge

Claro is a telecommunication company in Latin-American with a large base of mobile phone users in Colombia (more than 5million). It currently provides a payment app Claro-Pay. The challenge asked participants to develop a proof of concept of an application(s) to be integrated into their app that would consume the API’s currently hosted on their sandbox.

Our team proposed a financial marketplace where institutions and individual investors could create pools of available resources to be lent out at competitive interest rates to individuals with a credit score derived from Claro’s API’s. These microloans would be automatically granted if the applicant fulfilled some requirements. A smart contract within the platform would determine a match between lenders and borrowers.

The solution consisted of two applications: TuCredito (MyCredit) and YoFinancio (MyLoan) which are the two sides of the market.

We are very proud of what we accomplished during the four weeks of the event and we thank the organizers for inviting us to participate. 

SputniQ – Smart Experimental Data Repository

Most research-driven companies have many different data sources used by their teams. The result is a system of data silos characterized by: different data models, different vocabularies for common concepts and different levels of contextual information. This disconnection affects innovation.

The solution is an ontology-driven data integration tool that brings together data and semantics to create semantified-data. SputniQ is a proof of concept within the chemical domain that illustrates the value of adding semantics to the data.

The user interface provides information on different chemical experiments that can be presented and used in a standardized format by different teams.

Journal of Research Objects PoC

Open science is a movement that promotes open access to research data, publications, and scientific collaboration. It promises to increase transparency, provide reproducibility by reusing scientific datasets and increase trust in scientific collaboration. Blockchain fits the mindset of open science because of its transparency and decentralized nature.

This project create a proof of concepts of a Hyperledger Fabric-based “Scientific Journal” which could be used to share all the research objects that were produced during the research. These objects (Docs, Videos, Images, Code, Data sets) will be stored in a decentralized manner using IPFS (Inter-Planetory File System). The project was developed during the Google Summer of Code 2019 and proposed by the Open Bioinformatics Foundation and VIVO.

The applications developed and a detailed explanation of the solution is in the Journal Of Research Objects repo.

We are proud that some of our collaborators and researchers were part of this project that reflect our business values and research interest, we thank Google and the Open Bioinformatics Foundation for supporting this proof of concept.

Fixed income portfolio App

Using estimated historical returns from a set of bonds we design a tool to estimate and compare different portfolio optimization techniques. The application has an R statistical software backend that generates the estimation of the different sets of restricted and unrestricted portfolios. A Shiny app is used to provide a frontend application that allows non-technical users to select bonds and use historical data to estimate different portfolio statistics (returns, duration, Sharpe, ratio) using a large range of predetermined portfolio models.

In addition, users can select the end results on the chosen portfolio allocation to determine portfolio performance and risk metrics.

The combination of R and Shiny app provide applications that are quantitatively robust providing the full benefits of innovative techniques in asset management, but most importantly they give access to upper management to support their decision-making process using the results provides or by quickly deriving new result by adjusting different options on selected assets, portfolio restrictions and metrics.

EIT health ontology development

EIT Health as part of the European Institute of Innovation and Technology is in charge of fostering innovation in health and ageing, by bringing together business, research and education.  

In order to bring together the different partners in the network, EIT Health was interested in a technological solution to classify grant applications according to outcomes and technologies being used and facilitate interactions across innovators according to technologies, outcomes, products, medical specialities, diseases, location, etc.

Using semantic web technologies members of our team designed ontologies across EITH Ecosystem and implemented the infrastructure need to share structured and standardized knowledge across the members of the EIT Health network. 

We are proud that some of our collaborators and researchers were part of this project that reflect our business values and research interest.

Second place in the Blockchain Challenge (

¿Qué es lo que debes incluir en una publicación en el blog? Contenido útil, específico a la

In September 2019 we participated in the Blockchain Challenge (Hackathon) organized by (a public sector initiative to foster the development of IT capabilities in Colombia).

The Hackathon’s objective was to develop a solution and proof-of-concept of a blockchain solution that would facilitate the management of documents of public interest.  

Using Hyperledger Fabric we two solutions CERVER API and CERVER Verificator so that public institutions could issue an abstraction of any text-based document onto a blockchain. This abstraction was represented by the Hash of the document that would be registered onto the blockchain. This process is done using a Rest-API. The Verificator provides an application so that any text-based document could be checked against the authentic copy stored in the blockchain.

The applications developed and a detailed explanation of the solution is in the CERVER repo (in spanish).

The solution provided by the Linking Data Team obtained second place during the Hackathon.

We are very proud of what we accomplished during the four days of the event and we thank the organizers for the recognition and for inviting us to participate.
